Claws Mail has a high number of configurable options and, in order to keep 
the binary small and fast, some of these preferences which are not widely 
used are not provided with a graphical interface for inspection and/or 
modification. Users wanting to edit such preferences had to face editing 
the configuration text files directly; now it is possible to do so with a 
convenient GTK2 interface using Clawsker.  

This requires locale-gettext and perl-gtk2.
